However, inversion results are tool dependent, limiting the applicability of the results. More recently (Heidari et al...

In the cemented zones, on the other hand, there is an increase in shear velocity due to the significant reduction in porosity. The fact that the muddy carbonates exhibit porosity may contribute to relatively lower DENS...
